Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Coral mass bleaching
FOURTH MASS BLEACHING: US government scientists confirmed that the world is facing its fourth mass coral bleaching event, which is on track to be the “most extensive on record”, the Guardian reported. Mass coral bleaching is a phenomenon of the climate change era, first occurring in 1998, the story said. It added that 54% of ocean waters with coral reefs have experienced heat stress high enough for bleaching.
BARRIER BREACHED: The Great Barrier Reef – the world’s largest coral reef – has been through its most acute and widespread heat stress event ever, Coral Reef Watch confirmed to the Guardian. Coral reef scientist Prof Terry Hughes told the New York Times that the “levels of heat stress measured in Florida, across the entire Caribbean, and now on the Great Barrier Reef are off the charts”.
THE BIG DRY: Meanwhile, scientists in the Conversation explained the causes of a mass vegetation “die-off” in Western Australia’s forests and shrublands in February 2024, as the region “sweltered” through its hottest summer on record. “Just like a coral bleaching event, plants are responding to the cumulative stress of the unusually long, hot and dry summer,” the authors wrote.
World Bank spring meetings
BETTER HAVE BILLIONS: All eyes were on the World Bank and International Monetary Fund (IMF) spring meetings in Washington DC this week. As civil society and economists said wealthy nations must pledge billions more in aid through the bank to tackle climate change, president Ajay Banga told journalists at the meeting “the climate crisis would be a priority” for the bank going forward, the Guardian reported. Experts quoted by the newspaper, however, questioned the bank’s willingness to reform “in a race against time”.
DEBT TRAP: While the “long-simmering theme” of who should pay for climate damages raised its head again, debt was at front and centre at the meetings, the Financial Times reported. A report quoted in a Climate Home News comment by Asian debt activist Lidy Nacpil warned that 47 developing countries could go bankrupt from climate spending, but cancelling fossil fuel debts could free up the money needed.
LUXURY LOANS: Elsewhere, a Climate Home News investigation found that the World Bank counted support for five-star luxury hotels in Senegal as climate finance. Fishermen told the publication that the hotels had “exacerbated erosion” in their area.
Dubai floods
DUBAI FLOODS: The UAE was hit by an intense storm, with almost a year and a half’s worth of rain pummeling the capital of Dubai on Tuesday, the Independent reported. The country experienced its heaviest rains in 75 years, said national meteorological authorities quoted in the Financial Times. The newspaper added that more than a dozen people were killed in neighbouring Oman. The rains were likely exacerbated by climate change, reported Reuters.
SEEDING DOUBT: While a Bloomberg article citing one person initially blamed “cloud-seeding” for the extreme rainfall, multiple meteorologists quoted in different outlets including the Guardian and the Associated Press debunked such claims. “You can’t create rain out of thin air per se and get six inches of water,” meteorologist Ryan Maue told AP.
DEJA VU DISASTER: Flash floods, lightning and heavy rain also claimed 63 lives in Pakistan, with the northwestern province of Khyber Pakhtunkhwa recording the most fatalities, the Associated Press reported. In Baluchistan, authorities declared a state of emergency, with more rains expected amid rescue and relief operations.
Around the world
- INDIA VOTES: The first phase of voting in India’s general elections began today, as millions queued in scorching summer temperatures. Carbon Brief mapped where key national parties stood on climate change in their election manifestos.
- DEFORESTATION DROPS: Deforestation on Indigenous lands across the Amazon has declined by 42% since last year and dropped to a six-year record low, according to a report by Brazilian research institute Imazon cited by O Globo.
- ECUADOR ENERGY EMERGENCY: On Tuesday, Ecuadorian president Daniel Noboa declared an “energy emergency”, after an El Niño-driven drought hit hydropower production and led to country-wide power cuts, Reuters reported.
- MORE FOOTWORK, MORE ENERGY: Scientist and Mexico’s election frontrunner Claudia Sheinbaum unveiled a $13.6bn investment plan for solar, wind, hydro and gas projects, Reuters reported, calling it a “significant shift” from the current president’s oil-first priorities.
- SCOTLAND SETBACK: The first country in the world to declare a “climate emergency” is “ditching” its ambitious target of reducing emissions by 75% by 2030, BBC News reported, after failing to meet eight of its 12 last annual targets.
- SBTi CONTROVERSY: The Science Based Targets initiative, the leading arbiter of corporate climate targets, said there was “no change” to its standards, after an earlier suggestion that companies might be able to use carbon offsets to meet their goals led to a staff revolt, the Financial Times reported.
$38 trillion
The annual cost of rising temperatures, heavier rainfall and more frequent and intense extreme weather by 2049, under a medium emissions scenario, according to a new study by Germany’s Potsdam Institute for Climate Impact Research.
Latest climate research
- The Atlantic hurricane season could increase by well over a month (between 27 to 41 days) in the future because of the combined impact of climate change and natural climate variability, according to new research in Geophysical Research Letters.
- Marine animals seeking cooler temperatures as oceans warm could end up in areas where they will be exposed to deadly cold snaps, new research found. Carbon Brief had all the details.
- A new World Weather Attribution study found that El Niño was a “key driver” of a current severe drought in southern African countries, while climate change did not play as significant a role. A second WWA study found that an extreme heatwave striking the Sahel region between the end of March and the beginning of April would have been impossible without climate change.

Captured

New documents obtained by Carbon Brief as part of a freedom-of-information (FOI) request revealed that the UK government reclassified nearly £500m in humanitarian aid meant for war-torn nations as climate finance, in a bid to help meet its pledges under the Paris Agreement. According to Carbon Brief analysis, the humanitarian projects in nations such as Afghanistan, Yemen and Somalia being “double-counted” as climate finance have no explicit link to climate action. While the UK was previously viewed as setting higher standards than other countries on climate finance, experts told Carbon Brief that the government’s new approach of repackaging development and humanitarian aid instead of providing new money “risks breeding cynicism and mistrust”.

Elections in India’s coal and elephant country
On the eve of India’s general elections, Carbon Brief travels to the central Indian state of Chhattisgarh to speak to Indigenous communities protesting against coal mining in their sacred Hasdeo Arand forest.

On the winding hill road to the Hasdeo Arand forest, I was told by Indigenous activists to not get my hopes up for what I would – and would not – get to see. “Things are tense,” said an anxious Ramlal Kariyam on the phone to me. A thatched forest camp on the edge of the Parsa East Kete Basan (PEKB) coal mine was burned to the ground at 2am on 25 March, days before my visit. Police are still investigating the incident.
The camp was the epicentre of two-year-long relay protests to save one of India’s last contiguous tracts of dense sal forest from being clear-felled for coal. I had hoped to see the PEKB mine’s expansion and signs of rapid deforestation, but did not want to put villagers at risk. What I did not count on seeing through the sal trees on the side of the road was an elephant.
For years, India’s forest and state authorities ignored and concealed the presence of an elephant corridor in Hasdeo Arand, as they approved further fragmentation of what was once a “no-go” forest for coal mining. Even a spanner-like verdict in 2014 from India’s top environmental court acknowledging elephant presence and cancelling forest permits could not pause the excavators: its judgement remains stayed by India’s supreme court.
Mining in Hasdeo Arand began with the Bharatiya Janata Party (BJP) in power at the state level and the Congress party at the centre. But it gained pace after Modi assumed power at the national level in 2014. In 2018, voters in these districts gave Congress its most comprehensive victory in Chhattisgarh, after giving assurances that it would put Indigenous rights first. Instead, Congress greenlit the clearing of even more tracts of forest for coal and was voted out last December.
“There’s no relief for us in coal areas…In 2014, we passed resolutions in all our villages saying that there is very dense forest here that should never be bartered for coal, but the government has continued auctioning our lands based on falsified consent,” alleged Umeshwar Singh Armo, the 43-year-old chief of the village of Paturia, speaking to Carbon Brief in the spartan mud office of the Save Hasdeo Movement (pictured above). “We’ve tried every democratic, peaceful means to talk to the government, but nothing has happened.”
While mining was slow to first begin, its reserves have been exhausted faster than expected. “Brother, how much coal do you want? They’re mining with such speed that they can finish a place’s wealth in five years,” said Ramlal. “When I’m sitting alone, I often think to myself: Will we be able to save this place? When we’re displaced, what will happen to all the other creatures here? The state is extinguishing so many lives and species for just one man.”
The only thing that has been able to significantly stop more coal blocks from going under the hammer? Elephants.
In 2021, the state cabinet agreed to establish the stalled Lemru elephant reserve. In 2022, Chhattisgarh’s then-chief minister from the Congress party told the Modi government’s coal ministry that two coal blocks – including Gidhmuri-Paturia where Singh lives – should not be mined because they fall within the elephant reserve’s boundaries.
“Both [Congress and BJP] governments [state and national] work for the benefit of mining companies, but at least the Congress listens to democratic movements like ours that oppose mining,” said Singh. “The BJP, it doesn’t have that. If forests are finished, villages are finished, other species are finished, it makes no difference to them. The many laws that exist are all broken and made subservient to coal, they can magically turn dense forests into scrub forests when it suits them.”
As of last week, the movement has rebuilt its protest camp and is considering supporting Indigenous-led parties. Singh is defiant. He concluded:
“For the longest time, it’s just these two parties that called the shots, and yet both parties lost when they failed to keep our movements in mind. If you want to take our forest land from us, the very least you can do is to talk to us about it.”

Climate Change
Climate adaptation in Africa needs investment, not imported solutions
Ellen Davies is head of programmes at the African Climate Foundation and is based in Kenya. Wole Hammond is programme officer for adaptation and resilience at the foundation, based in Nigeria.
For generations, African communities have lived on the frontlines of climate disruption, managing erratic rainfall, prolonged droughts and the slow erosion of their livelihoods, which depend on predictable seasons.
When the rains failed across Southern Africa in 2024, it was but the latest chapter of a crisis already long underway. During that season, maize crop failures of 40-80% devastated farming communities in Zambia, Zimbabwe and Malawi, where roughly 70% of people depend on rain-fed agriculture. Governments already stretched by debt were forced to raid development budgets, trading long-term growth for emergency relief.
Then came the floods. In early 2026, parts of Mozambique, Zimbabwe and South Africa received over a year’s worth of rain in days. More than 2 million people were affected. In East Africa, drought has displaced nearly 62,000 people in Somalia this year alone, with nearly one in four Somalis now facing acute food insecurity.
This is what climate change looks like on the ground – not parts per million or diplomatic jargon, but whether a school stays open after floods cut off the road, whether a clinic can function in extreme heat, whether a country can still invest in its future when every year brings another disaster bill.
As Nigeria rails at loss and damage “mirage”, fund boss assures money is coming
Africa as a continent contributes the least to global emissions yet bears a disproportionate share of the consequences. Nine of the ten countries most vulnerable to climate change are African. As livelihoods collapse and rural economies fail, migration pressures will intensify, driven by climate change intersecting with poverty, conflict and constrained opportunity.
Chronic under-funding
Europe is only now beginning to experience, in more limited form, what African communities have navigated for decades with far less fiscal space, thinner insurance coverage and fewer resources for recovery. With El Niño conditions confirmed and a “super” version of the naturally occurring weather pattern possible later this year, the pressure is set to intensify further.
In Africa, climate action is fundamentally a development challenge where adaptation and mitigation must go hand in hand. Building a solar grid and flood-proofing the road that serves it are not separate agendas. Yet for too long, the global climate conversation has prioritised mitigation while leaving adaptation – the work of protecting lives, livelihoods and economies in a changing climate – chronically under-funded.
The result is three compounding gaps. A visibility gap: much of Africa’s adaptation work remains under-documented and under-recognised in global climate narratives. A financing gap: capital does not flow at the scale or speed required to the people and institutions best placed to use it. And a decision-making gap: too many solutions are still designed elsewhere and imported into African contexts, rather than backing African-led platforms to scale what is already working.

Solutions ready for finance
The solutions exist. Rwanda’s green investment fund has mobilised climate finance at national scale through its own systems. Egypt’s Nexus of Water, Food and Energy programme has shown how integrated planning can stretch limited resources across interdependent systems.
Zambia’s Presidential Irrigation Initiative is building climate-resilient food production from the ground up. In Pata, Senegal, a solar irrigation project has unlocked agricultural production and created jobs, demonstrating how integrated investments in water, energy and livelihoods can deliver resilience and development gains simultaneously.
In South Africa, the African Climate Foundation’s work with the South African Local Government Association (SALGA) is supporting district municipalities to assess their climate risks and develop fit-for-purpose Climate Action Plans, building adaptation capacity where it is needed most – at the local level.
These are not pilot projects waiting to be validated. They are working systems waiting for investment.
Closing the gaps requires a decisive shift in posture from global finance, philanthropy and development institutions. It means backing country-led platforms that can prepare, aggregate and finance adaptation projects. It means investing in place-based initiatives grounded in local knowledge.
French court rules Total must revise climate plan to account for all emissions
It means fostering intra- and inter-continental collaboration, so that lessons from Kigali inform decisions in Nairobi and innovations in Lagos reach communities in Dakar. And it means treating adaptation as core economic infrastructure, not charitable relief.
Invest now for future gains
The economic case is clear. Every dollar invested in climate adaptation returns an estimated four dollars in benefits on average – and up to five in the poorest economies. Under-investment in African adaptation is as economically irrational as it is morally unjust.
The world depends on Africa’s food systems, its young workforce – the majority of the continent’s population is under 25 – and its minerals. Several African countries supply a substantial share of the copper, cobalt and other critical materials underpinning the global clean energy transition.
Drought in Zambia has already shown how climate stress can disrupt hydropower, electricity supply and mining output. A transition that depends on African minerals cannot afford to ignore African climate resilience.
The world can continue to under-fund adaptation and pay repeatedly for emergencies, instability and lost development. Or it can invest now in the people, institutions and systems already doing the work on the ground in Africa, not in solutions imported from elsewhere.
Africa has the agency, the knowledge and the platforms. What it needs is the finance to match. A super El Niño will not wait for consensus to form. Neither, frankly, should we.

DeBriefed 26 June 2026: Heat records broken across Europe | London climate action week | Introducing ‘Project Cosmos’
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Record Europe heat
HOTTEST EVER: The UK broke its temperature record for June twice this week, while France recorded its hottest day ever two days in a row, reported the Guardian. The Times reported that temperatures reached 36.7C in Somerset on Thursday, as the “London Ambulance Service had its busiest-ever day for life-threatening emergencies”.
FRANCE FRYING: French newspaper Libération said that temperatures reached as high as 44.3C in the south-western commune of Pissos on Wednesday. Spain also recorded its highest daily average temperature for June, said BBC News. On Thursday, Switzerland also had its hottest June day, when temperatures reached 37C in four locations, reported SwissInfo.
CLIMATE LINK: CNN covered a rapid analysis from the World Weather Attribution service finding that fossil-fuelled climate change has made this heatwave the most severe and widespread in Europe’s history. Carbon Brief covered the broken heat records, explaining the influence of climate change.
‘Electrifying’ London talks
‘LONDON COOKING’: In a sweltering, packed-out event at London climate action week, UN chief António Guterres quipped that “London is not just calling, it’s cooking”, reported Edie. Guterres also used his address to release a “global call to action on methane” and to call on artificial intelligence companies to reveal their environmental impact and source their power solely from renewables by 2030, said the publication.
‘ELECTRIFY NOW’: Elsewhere, dozens of governments, led by the EU and the UK, committed to throwing “their political weight” behind a rapid electrification of the world’s economy, according to Climate Home News. A high-level summit in London’s Mansion House saw energy ministers and business leaders, joined by Guterres, in “calling for faster action to curb demand for oil, coal and gas by powering homes, industry and transport with clean electricity”.
FOSSIL TRANSITION: At the same event, ministers from Colombia and the Netherlands, the co-hosts of the world’s first summit on transitioning away from fossil fuels in April, unveiled a report on their key takeaways. It comes after the current Colombian government has been ousted by a presidential election defeat to a fossil-fuel-supporting Trump ally. Carbon Brief examined what this could mean for the world’s energy transition.
Around the world
- UK TARGET: The UK parliament has approved its “seventh carbon budget”, aimed at cutting emissions 87% below 1990 levels by 2040.
- TOTAL ACCOUNTABILITY: A French court has ordered oil-and-gas giant TotalEnergies to account for the emissions from the use of its products, following a case brought by a climate NGO, reported Le Monde.
- METHANE RULES: The US, Qatar and other major energy exporters have urged the EU to “rewrite planned methane emissions” rules for oil-and-gas imports, saying that the policy could disrupt fuel supplies to Europe, according to Reuters.
- CHINA MESSAGE: China’s special envoy for climate change, Liu Zhenmin, said at the World Economic Forum that energy shortages triggered by the Iran war should be a “lesson to countries to accelerate their energy transitions”, reported Bloomberg.
- US WEBSITE REVIVED: Former US government workers have “recreated a valuable climate-science website” shut down by the Trump administration last year, said the New York Times.

(For more, see Carbon Brief’s in-depth daily summaries of the top climate news stories on Monday, Tuesday, Wednesday, Thursday and Friday.)
Captured
The UK government’s official climate advisers, the Climate Change Committee (CCC), has released its latest progress report, emphasising that faster electrification is the best way to secure lower energy bills and stronger energy security. Electrification has shot up the agenda in recent months, with the COP31 presidency calling for countries to back a global goal for 35% of “final” energy to come from electricity by 2035. The text of the CCC’s latest report uses the word “electrification” far more often than previous editions, as shown in the figure above. See Carbon Brief’s in-depth breakdown of the CCC’s latest advice.

Introducing ‘Project Cosmos’
Carbon Brief explains how it built a major new database of climate science research and unveils a new ranking of the 500 most highly cited publications, authors and institutions in climate science.
This week, Carbon Brief launched Project Cosmos – the world’s largest and most complete database of climate change research.
The database features more than 1.8m academic papers, books and reports, capturing the vast body of human knowledge about climate change that has accumulated over more than a century of academic study.
The climate science “universe” is based on reports from the Intergovernmental Panel on Climate Change (IPCC), which are recognised as the world’s most authoritative summaries of the latest climate science.
Since its first report was published in 1990, humanity’s knowledge about human-caused climate change has ballooned. The IPCC has published six sets of reports in total – each one longer than the last.
In total, IPCC reports reference more than 100,000 other papers, books and reports. This is the core of our climate science universe. Carbon Brief then built on this core, by looking at four other sources of data. Read more about how the Cosmos database was created here.

Every single publication in the Cosmos database is linked to at least one other through references. Visualising these links reveals a “galaxy” of references.
In the image above, each colour and cluster reveals different topics and densities of research. Explore the galaxy in an interactive map.
Cosmos 500
As part of an initial wave of preliminary analysis to demonstrate the scope of the Project Cosmos database, Carbon Brief has ranked the 500 most highly cited publications, authors and institutions in the database.
The most highly cited climate scientist is Prof Philippe Ciais, who has spent almost four decades researching the planet’s carbon cycle – and the ways in which humans have been impacting its balance. Carbon Brief recently interviewed Ciais in Paris.
The US tops the tables for the most highly cited authors and institutions. Almost half of the 500 most highly-cited authors are from US institutions. This raises particular concerns for the future of climate science, as US climate scientists and institutions are coming under attack under the Trump administration.
Experts from global south countries account for only 4% of all authors in the Cosmos 500. China stands out as the most highly-cited global south country. Meanwhile, only 10% of authors in the Cosmos 500 are women.
There are many possibilities for future avenues of research using the Cosmos database. Over time, the database could be used to reveal, for example, how interest in different areas of climate science has changed over time, plus identify potential knowledge gaps and, thus, opportunities for future research.
Carbon Brief invites researchers – including academics, journalists and analysts – to submit their own proposals for co-authored studies, literature reviews and analytical projects. Proposals should be sent to cosmos AT carbonbrief DOT org.

Q&A: What change of power in Colombia could mean for world’s fossil-fuel transition
Over the last four years, Colombia has emerged as one of the most vocal advocates for the world to transition away from fossil fuels.
Under the leadership of leftist politician and economist Gustavo Petro, it became the first major oil-and-gas producer to commit to halting all new fossil-fuel expansion.
In April, the nation hosted a first-of-its-kind meeting of countries on transitioning away from fossil fuels, alongside the Netherlands, in the Caribbean city of Santa Marta.
The meeting concluded with a promise for a new “Santa Marta process” spearheaded by Colombia and the Netherlands, a movement of countries that would continue to push for a transition away from fossil fuels at home – and at international climate talks.
But on 21 June, an ally of Petro suffered defeat in a presidential election runoff against Abelardo de la Espriella, a hard-right populist and favourite of US president Donald Trump, who has pledged to boost oil production and pursue “fracking to the max”.
Below, Carbon Brief examines what the loss could mean for Colombia’s stance on fossil fuels, as well as international efforts to transition away from coal, oil and gas, including at the COP31 climate summit in Turkey in November.
- How could the election defeat change Colombia’s stance on fossil fuels?
- How could it affect international efforts to transition away from fossil fuels?
- How could efforts to transition away from fossil fuels feature at COP31?
How could the election defeat change Colombia’s stance on fossil fuels?
In 2022, Petro became Colombia’s first left-wing president in recent history.
Under his leadership, Colombia became the first major oil producer and exporter to halt all new fossil-fuel expansion, boosted renewable energy and saw a sustained decline in deforestation.
At the COP28 summit in 2023, Petro announced that Colombia would become the first major oil exporter to sign the fossil-fuel non-proliferation treaty, a pact to legally control fossil-fuel production and use.
Successive Colombian environment ministers became among the most vocal supporters of transitioning away from fossil fuels at UN climate talks.
This included former minister Susana Muhamad, a political scientist and environmentalist who stepped in to lead the most recent UN biodiversity summit in 2024 after original host Turkey was forced to withdraw following earthquakes.
She was succeeded by Irene Vélez Torres, a former academic who led calls for a “fossil-fuel roadmap” to be part of the formal outcome at the COP30 summit in 2025.
At the sidelines of COP30, Vélez Torres and Netherlands climate minister Stientje van Veldhoven announced plans to co-host a first-of-its-kind summit on transitioning away from fossil fuels in Colombia in April 2026.
(In the end, countries failed to agree to a formally negotiated “fossil-fuel roadmap” at COP30. However, the Brazilian COP30 presidency promised to bring forward a voluntary roadmap instead, informed by the Santa Marta summit.)
Some 57 countries – representing one-third of the world’s economy – participated in the event, with officials describing it as “refreshing”, “highly successful” and “groundbreaking”, according to Carbon Brief’s reporting from Colombia.
The meeting concluded with a range of outcomes, including a second fossil-fuel transition summit to be co-hosted by Tuvalu and Ireland in 2027.
In stark contrast to Petro’s government, new hard-right populist president Abelardo de la Espriella has promised to quickly boost new fossil-fuel and mining projects, including by “fracking to the max”.

De la Espriella has also promised to build 10 “mega prisons” inside Colombia’s Amazon rainforest.
He has not yet commented on whether he will withdraw Colombia from Santa Marta’s “coalition of the willing”.
How could it affect international efforts to transition away from fossil fuels?
Just two days after the Colombian government’s election defeat, environment minister Vélez Torres took to the stage at London climate action week, alongside Netherlands climate minister van Veldhoven, to present a report on key takeaways from the Santa Marta summit.
The report, written before the election loss, speaks of an ongoing “Santa Marta process” to accelerate the global transition away from fossil fuels. It says that this will be coordinated by Colombia and the Netherlands, along with the two appointed co-hosts of the second conference on transitioning away from fossil fuels, Tuvalu and Ireland.
Acknowledging that this was likely to be one of her last addresses as Colombia’s environment minister, Vélez Torres told the audience that, going forward, the Santa Marta process must be resilient to “political setbacks”.
At the sidelines of the event, Vélez Torres told Carbon Brief that the work her government has done “cannot be erased”, despite a change in power. She said:
“Right now, we are facing the dark nights, this will really shift the politics in terms of energy position and environmental protection. But we are certain that our legacy will continue. It goes beyond governments.”
Dutch minister van Veldhoven told Carbon Brief that the plan for the “Santa Marta process” is to hold fossil-fuel transition summits in a different country every year, with two new co-hosts each time. This could help weather political shocks, she said:
“We know that every couple of years there will be elections. That is why [we have] the idea of rotating presidencies and chairmanships…while we make sure we make use of existing secretariats and organisations that are not subject to political changes every couple of years.
“In that combination, we hope to create a historic legacy and continue to drive the process forward, but also [create space for] a new energy from two new countries every year that bring their own perspective and their own dynamic.”
Although new countries could drive the process forward without Colombia, there are few major oil producers that have shown the same level of commitment to transitioning away from fossil fuels.
Ana Toni, an economist and CEO of the COP30 summit in Brazil, told Carbon Brief at London climate action week that the world will “miss the leadership of Colombia”, but added:
“Not one country will stop this movement. All countries need to chip in. There isn’t one leader for this topic. Everybody needs to join forces.”
How could efforts to transition away from fossil fuels feature at COP31?
At London climate action week, Colombia and the Netherlands presented their Santa Marta report to the Brazilian COP30 presidency.
The COP30 presidency is due to release a voluntary international “fossil-fuel roadmap” ahead of COP31 in Turkey in November, which it has promised will be informed by the takeaways from Santa Marta.
Speaking at the sidelines of London climate action week, Colombia and the Netherlands added that they have had “constructive” conversations with the COP31 co-presidencies, Australia and Turkey, about how to incorporate the discussions from Santa Marta.
Colombian environment minister Irene Vélez Torres told a small group of journalists:
“We had this very interesting conversation with COP31 and they were clearly open to suggestions about what is needed in the discussion in Turkey, and we were explicit about the need to engage with the phasing out of fossil fuels.”
However, both Colombia and the Netherlands added that they were unsure of how this might work in practice.
When asked about whether the Santa Marta discussions could be incorporated into formal COP texts, they were keen to emphasise that all the conversations in Colombia were specifically not negotiations.
They added that they were unsure of whether the group of 57 countries that gathered in Santa Marta would appear as a collective at press conferences or events at the COP31 summit.
